Title: Selective stepping motor control circuit
IPC: H02P8/14
Filed: 1974-04-30
Abstract: 1465573 Control of stepping motors; counting apparatus CARL ZEISS JENA VEB 30 April 1974 [3 May 1973] 18828/74 Headings G4A and G4D [Also in Division H2] A circuit to provide selective control of a stepping motor for whole or halved angle stepping comprises a bidirectional shift register 1 having five J-K flip-flops 2-6 whose outputs A1-A5 control the respective motor windings through power switches (not shown), a sychronising circuit 7 whose signal SE determines a desired mode of operation of the register (i.e. "L" or "O" states of the flip-flops 2-6) by entering appropriate information into it at the start of a motor control operation, and a switching circuit 8 consisting of a flip-flop 11 responsive to clock pulses T, a gate circuit 9 responsive to a signal W which has an "O" value to produce whole angle steps of the motor or an "L" value to produce halved angle steps, a digital store 10 to store the signal W and NAND gates 12, 13 controlled by members 10, 11 and respectively connected to the J and K inputs of the flip-flops 2-6. Whole angle stepping.-With an "O" signal W, a signal SE having an initial "O" value to produce a desired one of three register modes (e.g. A1 and A2-L, A3, A4 and A5-O) and a subsequent value "L" during motor operation, and an "O" or "L" signal at R to produce a desired direction of motor rotation, the gates 12, 13 both have "L" signal outputs independent of the state of flip-flop 11 and the clock pulses T produce an operation of the register 1 corresponding to that of a Johnson ring counter. Halved angle stepping.-With an "L" signal W and signals SE and R the same as before, the gates 12, 13 respond to the flip-flop 11 to have alternate "L" and "O" outputs, whereby the pattern of the flip-flop states in the register changes in a predetermined manner with alternate clock pulses (e.g. clock pulse O gives A1, A2-L, A3, A4, A5-O; pulse 1 gives A1, A2, A3-L, A4, A5-O; pulse 2 gives A2, A3-L, A1, A4, A5-O and so on). Gate circuit 9 is controlled by flip-flop 11 to block the signal W if it is changed to "O" during an inappropriate condition of the register (e.g. three flip-flops in the "L" state), the "O" signal being stored in 10 for release to the gates 12, 13 when the next clock pulse occurs and changes the register to the correct condition for whole angle stepping (e.g. two flip-flops in the "L" state).

Title: Coating method and apparatus
IPC: D04B15/06
Filed: 1961-05-25
Abstract: 975,508. Coating surfaces. PITTSBURGH PLATE GLASS CO. May 25, 1961 [June 8, 1960], No. 18878/61. Heading B2B. A method of coating a portion of the surface of a glass sheet curved to have portions removed from a first plane comprises supporting said sheet with a portion only of its curved surface disposed in the path of a spray, directing a spray of a coating composition along an axis extending from the spray origin towards said curved surface, moving said spray origin relative to said curved surface in a curved path which is in a plane substantially parallel to said first plane while simultaneously projecting said spray towards said curved surface. As shown, a suitable apparatus comprises a glassbinding lehr 6 and a coating station 13. At coating station 13 is suspended a telescopic arm 20 comprising an upper rigid shaft 21, which shaft has torsion-free movement longitudinally and transversely, and a lower portion comprising a hollow member 30 enclosing, and in slidable engagement with, a lower portion of said rigid shaft 21. Connected to the arm 20 are sprayheads 54 and 55. The carriage means for the sprayheads, comprising a pair of ball transfers 47 in contact with the upper sides of cam rail 86 of circular cross-section, are moved by a reciprocable motor-driven triangular plate 67 mounted on shafts 65 and 66 and connected to telescopic arm 20 by chains 80 and 81. A glass sheet 7 supported on mould 8 and mould carriage 9 is passed through lehr 6 by conveyer 10 to conveyer 12 which carries sheet 7 through coating station 13. On entering coating station 13 the sheet 7 is arrested, conveyer 12 is stopped and the carriage 9 is correctly positioned and oriented by members 15 adapted to engage the lateral edges of carriage 9. Then the electric motor 71 is switched on and the triangular plate 67 moves carrying with it the telescopic arm 20 whose path is determined by cam rail 86. Simultaneously with the actuation of motor 71 a compressor (not shown) is switched on which actuates the pneumatically controlled valves in the sprayheads 54 and 55 and causes coating composition to be sprayed, the composition being atomized by pressurized air. When the telescopic arm 20 reaches the end of its path the motor 71 and compressor are simultaneously switched off. The motor 71 is then automatically switched on again and the arm 20 moves in the opposite direction. After the arm has made a complete return journey the motor 71 is switched off and the glass sheet 7 is passed to an unloading station (not shown).

Title: Container filling machine
IPC: B65B31/04
Filed: 1968-04-22
Abstract: 1,205,488. Filling containers. A.T.A.D. APPROVISIONNEMENT-TRANSPORT AERIEN-DISTRIBUTION. 22 April, 1968 [24 April, 1967], No. 18941/68. Heading B8T. In a machine for filling a product, e.g. edible cream, under sterile conditions into valved containers R, a rotary drum 1 rotatably mounted on a stationary shaft 2 between two fixed distributer plates 3 and 4 is provided with external conduits 6 at the end of which are devices 7 for supporting and filling the containers. Radial ducts 8 in the drum communicate with the conduits 6 and also communicate in turn with ports (11, 12, 14, 15, 16), (10, 13), Figs. 3 and 4 (not shown), for successive operation of various stages in the filling cycle. On rotation of the drum 1 and supporting discs 28 and 29 by a motor 30, and the introduction of the container R to device 7, port (10) in plate 4 first communicates with duct 9 and the container is evacuated by means of a vacuum pump 18. On further rotation, duct 9 communicates with port (11) in plate 3, through which an asepticizer is introduced from a metering pump 20, and then with port (12) introducing sterilized air. The sterilized product, e.g. edible cream, is introduced from a metering device 22 through port (14) at the next stage, followed by a propelling gas through port (15). After removal of the filled container, sterilized air is introduced through port (16) to remove final traces of products. Each filling device 7 has a socket (23), Fig. 5 (not shown), for receiving the valve of an inverted container which is held in place by a cap carried by the disc 28 and movable downwards both to open the container valve and also depress a piston (24) to open a conduit 6. An alternative embodiment, Figs. 6-9 (not shown), has separate conduits (6a, 6b) connected to a drum (1a) conduit (6a) communicating with ports in plate (4a) only and conduit (6b) communicating with ports in plate (3a) only. Thus, materials in the process can be kept separate by introducing some in turn to the container via conduit (6a) and others via conduit (6b). The operation is similar to the previous embodiment, except that a rotatable lever-operated valve (37) is provided in the supporting head (7a) for selecting input from either conduit (6a) or (66). A lever (40) rotated by a cam controls this selection and a hollow needle (41) penetrates into the container. A drain pipe (44), occluded while the container is in position for filling, is provided in the cavity at the top of the head for evacuating waste material after removal of the container. Apart from the selection of different conduits for different materials, the operation is identical to the first embodiment.

Abstract: 958,209. Cigarette-making machines. MOLINS MACHINE CO. Ltd. June 2, 1960 [June 3, 1959], No. 19065/59. Heading A2C. The pressure drop across a tobacco filler, measured at 19, Fig. 1, is compared with that across a reference device 29 and variations in the difference cause adjustment of the trimmer blades 5. The filter is held by suction on a perforated conveyer 2 and a fan 22 draws air through a suction chamber 19 downstream of the trimmer 5 and through the reference device 29 which comprises a chamber with a restricted inlet. The pressures in the chambers 19, 29, are applied to a diaphragm 28 controlling a pressure amplifying device 33, 42, controlling a pressure responsive capsule 39 which actuates the control valve 81 of a hydraulic servomotor 11 to adjust the position of the trimmer blades 5. The apparatus for adjusting the blades 5 is similar to that of Specification 929,338. A rise in pressure in chamber 19, denoting a less dense portion of the filler, causes diaphragm 28 to rise which closes air bleed 36 in a compressed air pipe 35 to raise the pressure in pipes 35 and 38 whereby capsule 39 expands to cause servomotor 11 to move the discs 5 away from the band 2 to remove less tobacco and hence increase the amount of tobacco in the trimmed filler. The reference pressure device 29 comprises a chamber with a base with a number of slits 52, Fig. 3, therein which are controlled by an adjustable plate with similar slits, the pressure drop across the device being adjusted to that desired for the trimmed filler. A second suction device 6 may be used upstream of the trimmer 5 to sense variations in resistance to air flow of the untrimmed filter, the pressure variations being transmitted to a capsule 9 to adjust the trimmer as described in Specification 929,338. Specifications 854,736, 881,024, 895,733, 909,222 and 916,141 also are referred to.

[Also in Division F2] A control mechanism for a winch 23 on a rotatably telescopic crane boom 18 of a mobile crane 10 comprises a reversible winch operating hydraulic motor 26 mounted on the boom 18 a valve 34a on an operation platform 15 of the crane 10 for controlling the fluid flow to and from the motor 26, a brake mechanism 65 (see Division F2) mounted on the boom and coupled to the winch and a shuttle valve 80 interconnecting the hydraulic supply and return lines 61, 62 of the motor 26 and the brake mechanism for rendering the said mechanism inoperative when the motor 26 is operated. The winch 23 comprises a drum 51 freely mounted on a shaft 52 and drivingly connected therewith by an hydraulically operated clutch 130. The shaft 52 is driven through a reduction gear 53 and a shaft 56 from the motor 26. The brake 65 includes a brake drum 66 secured on the shaft 56 and partially surrounded by an adjustable arcuate brake shoe 67, the two ends of which are normally pressed together by a coil spring to normally brake the winch drive. The said spring is disposed in a housing 68 which also incorporates an hydraulic piston and cylinder, Fig. 3 (not shown), whereby the spring can be compressed to release the brake. The clutch 130 comprises a clutch plate 131 keyed to the winch drum shaft 52, a pair of clamptype shoes 132 mounted on a frame 133 integral with the winch drum 51 and which normally engage the plate 131 under spring pressure. These shoes may be disengaged from the plate by actuations of hydraulic piston or cylinder arrangements 134. The latter are energized by a foot pedal operated cylinder 141 on the operation platform 15 which pressurizes the fluid lines 144, 145, 148, 149 coupled by an hydraulic rotary distributer 40 and swivel couplings 146, 147. In operating the winch drum 51 to lift up a load hook 22 via the cable 21, the valve 34a is selected to cause pressurization of lines 37, 61 and passage 44 in the distributer 40 to operate the motor 26. For lowering, the load lines 36, 62 and passage 43 are pressurized, the fluid returning from the motor 26 to the fluid reservoir 31 via the lines 61, 37 and 38. The shuttle valve 80 is placed in the hydraulic circuit and allows the brake feed line 78 to become pressurized coincidental with pressurization of lines 61 or 62, the line 78 exhausting through line 101 which joins a bleed line 102 from the motor 26. A counterbalancing valve 110 (see Division F2) is placed in the line 61 which allows fluid to flow freely through line 61 into the motor 26 to cause raising of the load but restricts the flow through the line 61 in the reverse direction when the load is being lowered. The degree of flow restriction is governed by a cylindrical valve head having peripheral apertures along its length the longitudinal displacement past a valve seat 1 being controlled by a piston and cylinder arrangement pressurized by line 62b from line 62.
